Update to PHP7

When updating to VDV2018 you need to configure the Internet Informational Services (IIS) to use PHP7 instead of PHP5.2:

1. For VDV2018 and PHP7 to operate, the Visual C++ Redistributable for Visual Studio 2015 needs to be installed. Download and extract
   https://www.microsoft.com/en-us/download/details.aspx?id=48145 (vc_redist.x86.exe)
2. Got to Control Panel > System and Security > Administrative Tools > Internet Information Services (IIS) Manager
3. Under Default Web Site select the vdv directory and open up Handler Mappings by double clicking
4. Locate and select the PHP from earlier version and click and edit
5. Update the Executable field with the new path to PHP7. The new php-cgi.exe file can be located at C:\Vista Data Vision\db.web.browser\php7Note: After navigating to the php-cgi.exe location changing the File name extention from *.dll to *.exe
6. Next select the Server/Computer name in the IIS connections and open up ISAPI and CGI Restrictions by double clicking on that
7. Select the PHP extension and click on Edit
8. Update the ISAPI or CGI path field with the new path to PHP7 exactly the same way as for Handler Mappings earlier. The new php-cgi.exe file can be located at C:\Vista Data Vision\db.web.browser\php7
9. Final step is to restart the IIS. Select the Server/Computer name in the IIS connections and click on Restart
10. If VDV is not installed on the C-drive
    
    If Vista Data Vision is not installed directly under C:\ then one change must be made to the php.ini file located under /Vista Data Vision/db.web.browser/php7
    
    Find the following line:
    
    upload_tmp_dir = "C:\Vista Data Vision\db.web.browser\php7\upload_temp"
    
    Change it to the path where you have installed VDV. For example if VDV is installed on the D drive you would change the line to:
    
    upload_tmp_dir = "D:\Vista Data Vision\db.web.browser\php7\upload_temp"
11. Test the Web
    Note: If you want to see if PHP has been installed correctly create an info.php file and store it in \Vista Data Vision\db.web.browser\vdv_www folder. info.php file is just a text file and may be created using Notepad. The file should only contain the following php code.
    
    <?php
    phpinfo()
    ?>
    
    Open a Web Browser and type in http://localhost/vdv/info.php. You should see an information page on PHP. If you do not see this page, check that you have performed the steps above correctly.
